ЦитироватьExos suffers setback in reusable suborbital launch attempt

WASHINGTON — A reusable suborbital rocket developed by Exos Aerospace suffered a loss of attitude control seconds after liftoff on a test flight June 29, but the rocket was still able to glide safely back to Earth.

Exos' Suborbital Autonomous Rocket with GuidancE, or SARGE, rocket lifted off from Spaceport America in New Mexico at about 2 p.m. Eastern. In the company's webcast, the rocket started gyrating seconds after liftoff before disappearing from view.

Controllers were able to reestablish some control of the rocket, aborting the flight. The rocket deployed a drogue parachute and parafoil while venting unused propellant. The rocket slowly descended under that parafoil, landing within view of the launch pad 14 minutes after liftoff.

"We had a performance challenge on our gimbal control for one reason or another," John Quinn, chief operating officer of Exos, said in brief comments at the end of the company's webcast. "It's a very, very sad day. However, any day you recover a rocket it is a good day."

Quinn didn't elaborate on the problem that caused the anomaly after liftoff, but expressed optimism the problem will be quickly identified and corrected. "Great improvement from last time on the recovery," he said of the vehicle's landing. "We'll be doing this again soon."

This launch, called Mission 3 by Exos, came after two earlier flights of SARGE in August 2018 and this March. Both those launches suffered some issues that prevented them from reaching the edge of space, but in neither case were those problems as severe as for this flight.

The company thought those earlier problems had been corrected. Quinn noted on the webcast prior to launch that the company had identified 93 lessons learned from the March launch that they incorporated into Mission 3.

The rocket was carrying educational, research and technology demonstration payloads from nine customers on this launch, ranging from a dust aggregation experiment from the University of Central Florida to a biomedical experiment for the Mayo Clinic. Exos expected the rocket to reach a peak altitude of more than 80 kilometers if all went as planned, providing those payloads with a brief period of microgravity before returning to Earth.

A successful flight, the company said prior to launch, would have allowed the company to move into more routine commercial operations of the vehicle, including making it eligible for indefinite delivery/indefinite quantity contracts from NASA's Flight Opportunities program. "With a successful flight we will leave the testing phase," Quinn said in a pre-launch statement.

Exos also hoped a successful test would allow it to move ahead with a small orbital launch vehicle called Jaguar. That vehicle will feature a reusable first stage using technology developed for SARGE, and be capable of placing 100 kilograms into low Earth orbit. The first launch of Jaguar is planned for late 2022, and Quinn said on the webcast the company is starting to hire personnel to work on that vehicle.

Опубликовано: 25 июл. 2019 г.

Students fr om across the United States witnessed the launching of their experiments aboard a NASA suborbital sounding rocket Thursday, June 20, 2019, from the Wallops Flight Facility in Virginia. The rocket will carry 28 experiments (measuring acceleration, humidity, pressure, temperature and radiation counts) from the RockOn! Program. Participants in RockOn! receive instruction on the basics required to develop a scientific payload for flight on a suborbital rocket. After learning the basics in RockOn!, students may then participate in RockSat-C, wh ere during the school year they design and build a more complicated experiment.

Conducted with the Colorado and Virginia Space Grant Consortia, RockOn! is in its twelfth year and RockSat-C its eleventh year.

Shining (Star)light on the Search for Life
ЦитироватьSummary:
    [/li]
  • To find life on other planets, scientists look for traces of gases produced by living things


  • Some stars may produce these gases in a planet without life


  • The SISTINE sounding rocket studies stars to find which gases are valid signs of life


In the hunt for life on other worlds, astronomers scour over planets that are light-years away. They need ways to identify life from afar — but what counts as good evidence?

Our own planet provides some inspiration. Microbes fill the air with methane; photosynthesizing plants expel oxygen. Perhaps these gases might be found wherever life has taken hold.

But on worlds very different from our own, putative signs of life can be stirred up by non-biological processes. To know a true sign when you see it, astronomer Kevin France at the University of Colorado, Boulder, says, you must look beyond the planet itself, all the way to the gleaming star it orbits.

To this end, France and his team designed the SISTINE mission. Flying on a sounding rocket for a 15-minute flight, it will observe far-off stars to help interpret signs of life on the planets that orbit them. The mission will launch from the White Sands Missile Range in New Mexico in the early morning hours of Aug. 5, 2019.

When Earth Is a Bad Example
Спойлер
Shortly after Earth formed 4.6 billion years ago, it was enveloped by a noxious atmosphere. Volcanoes spewed methane and sulfur. The air teemed with up to 200 times more carbon dioxide than today's levels.

It wasn't for another billion and a half years that molecular oxygen, which contains two oxygen atoms, entered the scene. It was a waste product, discarded by ancient bacteria through photosynthesis. But it kick-started what became known as the Great Oxidization Event, permanently changing Earth's atmosphere and paving the way for more complex lifeforms.

"We would not have large amounts of oxygen in our atmosphere if we didn't have that surface life," France said.

Oxygen is known as a biomarker: a chemical compound associated with life. Its presence in Earth's atmosphere hints at the lifeforms lurking below. But as sophisticated computer models have now shown, biomarkers on Earth aren't always so trustworthy for exoplanets, or planets orbiting stars elsewhere in the universe.

France points to M-dwarf stars to make this case. Smaller and colder than our Sun, M-dwarfs account for nearly three-quarters of the Milky Way's stellar population. To understand exoplanets that orbit them, scientists simulated Earth-sized planets circling M-dwarfs. Differences from Earth quickly emerged.

M-dwarfs generate intense ultraviolet light. When that light struck the simulated Earth-like planet, it ripped the carbon from carbon dioxide, leaving behind free molecular oxygen. UV light also broke up molecules of water vapor, releasing single oxygen atoms. The atmospheres created oxygen — but without life.

"We call these false-positive biomarkers," France said. "You can produce oxygen on an Earth-like planet through photochemistry alone."

Earth's low oxygen levels without life were a kind of fluke – thanks, in part, to our interaction with our Sun. Exoplanet systems with different stars might be different. "If we think we understand a planet's atmosphere but don't understand the star it orbits, we're probably going to get things wrong," France said.

To Know a Planet, Study its Star

France and his team designed SISTINE to better understand host stars and their effects on exoplanet atmospheres. Short for Suborbital Imaging Spectrograph for Transition region Irradiance from Nearby Exoplanet host stars, SISTINE measures the high-energy radiation from these stars. With knowledge about host stars' spectra, scientists can better distinguish true biomarkers from false-positives on their orbiting planets.

To make these measurements, SISTINE uses a spectrograph, an instrument that separates light into its component parts.

"Spectra are like fingerprints," said Jane Rigby, an astrophysicist at NASA's Goddard Space Flight Center in Greenbelt, Maryland, who uses the methodology. "It's how we find out what things are made of, both on our planet and as we look out into the universe."

SISTINE measures spectra in wavelengths from 100 to 160 nanometers, a range of far-UV light that, among other things, can create oxygen, possibly generating a false-positive. Light output in this range varies with the mass of the star — meaning stars of different masses will almost surely differ from our Sun.

SISTINE can also measure flares, or bright stellar explosions, which release intense doses of far-UV light all at once. Frequent flares could turn a habitable environment into a lethal one.

The SISTINE mission will fly on a Black Brant IX sounding rocket. Sounding rockets make short, targeted flights into space before falling back to Earth; SISTINE's flight gives it about five minutes observing time. Though brief, SISTINE can see stars in wavelengths inaccessible to observatories like the Hubble Space Telescope.

Two launches are scheduled. The first, from White Sands in August, will calibrate the instrument. SISTINE will fly 174 miles above Earth's surface to observe NGC 6826, a cloud of gas surrounding a white dwarf star located about 2,000 light-years away in the constellation Cygnus. NGC 6826 is bright in UV light and shows sharp spectral lines — a clear target for checking their equipment.

After calibration, the second launch will follow in 2020 from the Arnhem Space Centre in Nhulunbuy, Australia. There they will observe the UV spectra of Alpha Centauri A and B, the two largest stars in the three-star Alpha Centauri system. At 4.37 light-years away, these stars are our closest stellar neighbors and prime targets for exoplanet observations. (The system is home to Proxima Centauri B, the closest exoplanet to Earth.)

Testing New Tech
Спойлер
Both SISTINE's observations and the technology used to acquire them are designed with future missions in mind.

One is NASA's James Webb Space Telescope, currently set to launch in 2021. The deep space observatory will see visible to mid-infrared light — useful for detecting exoplanets orbiting M-dwarfs. SISTINE observations can help scientists understand the light from these stars in wavelengths that Webb can't see.

SISTINE also carries novel UV detector plates and new optical coatings on its mirrors, designed to help them better reflect rather than absorb extreme UV light. Flying this technology on SISTINE helps test them for NASA's future large UV/optical space telescopes.

By capturing stellar spectra and advancing technology for future missions, SISTINE links what we know with what we've yet to learn. That's when the real work starts. "Our job as astronomers is to piece those different data sets together to tell a complete story," Rigby said.

University and community college students from across the country will complete their summer vacation on high note as they send their projects into space on a NASA two-stage Terrier-Improved Malemute suborbital sounding rocket Aug.12, 2019, from the Wallops Flight Facility in Virginia.

The projects are a mix of technology and science experiments including developing spacecraft reentry and thermal protection systems, measuring cosmic rays and gathering organic molecules in space for DNA sequencing,

The launch of the 44-foot tall rocket is scheduled between 5:30 and 9:30 a.m. EDT.  The backup launch dates are August 13 - 16.

After flying to around 91 miles altitude, the payload, with the experiments, will descend by parachute and is expected to land 15 minutes after launch in the Atlantic Ocean, about 64 miles off the Virginia coast. The experiments and any stored data will be provided to the students later in the day following sea recovery of the payload.

The NASA Visitor Center at Wallops will open at 4:30 a.m. on launch day for viewing the flight. The rocket launch is expected to be only seen from the Eastern Shore of Virginia and Maryland.

Live coverage of the mission is scheduled to begin at 5:10 a.m. on the Wallops the Wallops Facebook site.

The experiments are being flown through the RockSat-X program in conjunction with the Colorado Space Grant Consortium. RockSat-X is the most advanced of NASA's three-phase sounding rocket program for students.  The RockOn launches are at the entry level, then progress to the intermediate level RockSat-C missions and then RockSat-X.

Giovanni Rosanova, chief of the Sounding Rockets Program Office at Wallops, said, "RockOn and RockSat have shown to be valuable programs in developing the skills of our future scientists, technicians and engineers. As NASA returns to the Moon and goes on to Mars, these students will be needed in our future workforce to carry on these ambitious missions, as well as science missions to understand the planet Earth and our universe."

Participating institutions in this flight are the Arapahoe Community College, Littleton, Colorado; Community College of Aurora, Colorado; Red Rocks Community College, Lakewood, Colorado; College of the Canyons, Santa Clarita, California; the University of Puerto Rico, San Juan; University of Kentucky, Lexington; University of Maryland, College Park; University of Nebraska, Lincoln; and Hobart and William Smith Colleges, Geneva, New York.

Additional participants from West Virginia include West Virginia University, Morgantown; Blue Ridge Community and Technical College, Martinsburg; West Virginia State University, Institute; West Virginia Wesleyan College,  Buckhannon; and NASA's IV & V Facility in Fairmont.

RockSat-X is part of a three-tier program that introduces secondary institution students to building experiments for space flight and requires them to expand their skills to develop and build more complex projects as they progress through the programs. RockSat-X experiments are flown approximately 20 miles higher in altitude than those in  the RockOn and RockSat-C programs, providing more flight time in space

"This will be the ninth flight of a RockSat-X payload," said Chris Koehler, director of the Colorado Space Grant Consortium. "The program has provided opportunities for more than 1000 students to participate in developing an experiment for spaceflight, which has been beneficial as they have joined such organizations as NASA, the Jet Propulsion Laboratory, Space-X, Lockheed Martin, DigitalGlobe, Northrop Grumman and many others after graduation."

NASA's Sounding Rockets Program is managed at the agency's Wallops Flight Facility, which is managed by NASA's Goddard Space Flight Center in Greenbelt, Maryland. NASA's Heliophysics Division funds the Sounding Rockets Program for the agency.

The experiments being flown on this RockSat-X flight are:

Community Colleges of Colorado

The Debris Orbital Tumbler and Thermal Sensor (DOTTS) project is a collaboration between three community colleges in Colorado: Arapahoe Community College, Community College of Aurora, and Red Rocks Community College. Their primary experiment is to develop a cost-effective method to alter the trajectory of space debris in suborbital flight. The payload is designed to create an electrostatic field to attract small pieces of aluminum debris by charging a deployable rod with rabbit fur. Their secondary experiment is meant to expand their knowledge about an interesting discovery the team made during the launch of their 2018 experiment. They will be flying multiple pieces of 3D printed material made out of different types of plastic and in different shapes in order to better understand the effects of reentry conditions on 3D printed structures.
