Exos’ SARGE Rocket Reached 20 km Before Abort

An Exos Aerospace SARGE rocket reached 19.8 km (12.3 miles) before the flight abort after launch from Spaceport America on March 2, the company announced in a statement.

SARGE’s autonomous control system aborted the flight at about 65,000 ft after the rocket reached its instantaneous impact point (IIP) limit, Exos said. In essence, booster determined it was likely to land outside of the permissible range.

The flight had aimed to reach 80 km (49.7 miles). Despite the early abort, the company said it was pleased with the results of the second flight of the reusable booster, which previously flew last August.

EXOS Aerospace Launches SARGE Suborbital Rocket From Spaceport America

The reusable, suborbital rocket landed back in the desert under a parachute. No information yet on altitude.

Flight programs and associated payloads on the flight included:

SPACEedu… Help your school fund, build, fly and reuse CubeSat projects for their S.T.E.M research programs. Having already flown for many schools, Exos is literally taking education to a higher level.  P1. Arete’ Greater Nanticoke Area Trojans (space thermal energy transfer experiment).

SPACEbuild… Test or manufacture in space aboard an Exos vehicle for premium exposure to space flight conditions. The reduced cost of suborbital flights makes it a preferred risk mitigation step for qualifying orbital payloads. P2. NASA (Vibration Damper – TRL advancement),  P3. University of Central Florida (Dust Aggregation experiment – SPACE-2 NASA REDDI Payload), P4. Agronautics, LLC (Space hops & grain), P5. SOLGW  (memorabilia)

SPACEaid… Perform breakthrough medical research by leveraging the ability to test in the microgravity and vacuum of space.  With Exos we can return your payload within minutes of landing.  Our soft (5G) launch and fin stabilization means a gentle ride for your payload requiring less effort in payload design over other commercial launch options.  P6. Center for Applied Space Technologies (Sponsoring Mayo Clinic for two “BRIC66” payloads performing cell research)

SPACEship… Launch from Spaceport American in New Mexico and we’ll deliver your payload to space and eject it to perform your test outside our vehicle.*  (LEO target aboard our reusable (first stage) Jaguar vehicle – late 2022).

2018 Was Busy Year for Suborbital Flight Tests

There were 15 flight tests of eight suborbital boosters in 2018, including six flights of two vehicles — Virgin Galactic’s SpaceShipTwo and Blue Origin’s New Shepard — that are designed to carry passengers on space tourism rides.

The race to provide launch services to the booming small satellite industry also resulted in nine flight tests of six more conventional boosters to test technologies for orbital systems. Two of the boosters tested are designed to serve the suborbital market as well.

A pair of Chinese startups took advantage of a loosening of government restrictions on launch providers to fly their rockets two times apiece. There was also suborbital flight tests of American, Japanese and South Korean rockets.

Suborbital Flights Stopped Being So Humdrum in 2018

Throughout the Space Age, suborbital flight has been the least exciting segment of the launch market. Operating in the shadow of their much larger orbital cousins, sounding rockets carrying scientific instruments, microgravity experiments and technology demonstrations have flown to the fringes of space with little fanfare or media attention.

The suborbital sector has become much more dynamic in recent years now that billionaires have started spending money in it. Jeff Bezos’s Blue Origin and Richard Branson’s Virgin Galactic both made significant progress last year in testing New Shepard and SpaceShipTwo, respectively. Their achievements have raised the real possibility of suborbital space tourism flights in 2019. (I know. Promises, promises…. But, this year they might finally really do it. I think.)

GPS Glitch Limited Altitude of Exos SARGE Rocket

Space News reports that Exos Aerospace’s SARGE launch from Spaceport America last month failed to reach its intended altitude due to a glitch in its GPS system.

In a mission report provided by the company a week and a half after the launch, Exos said that a GPS receiver on the rocket stopped providing data during the rocket’s ascent. That triggered an automatic shutdown of the rocket’s engine 38 seconds after liftoff, versus a planned duration of 62 to 65 seconds, said John Quinn, chief operating officer of Exos, Sept. 5.

As a result of the early engine shutdown, the rocket reached a peak altitude of 28 kilometers, rather than the planned 80 kilometers. Quinn said an extrapolation of the rocket’s performance during that powered phase indicated the rocket might have been able to reach nearly 90 kilometers had the engine fired for the full duration.

The cause of the GPS unit malfunction in the rocket is still being studied. The unit started providing data again later in the flight, and an inspection turned up no obvious damage to the unit, cabling or antennas. There were separate dropouts of telemetry from the rocket during the flight, according to the mission report.

Reusable Booster to Conduct Test Flight at Spaceport America

SPACEPORT AMERICA, NM (NMSA PR) – EXOS Aerospace Systems & Technologies, Inc of Greenville, Texas, has selected Spaceport America for final testing of a reusable space launch vehicle known as SARGE (Suborbital Autonomous Rocket with GuidancE).

EXOS has completed the design, test and build; has received its FAA launch license and completed the final integration and test hovering for the rocket. A successful test flight is needed to solidify the company’s plans to use the technology as the basis for a planned reusable Orbital class vehicle, the company said in a press release issued Tuesday.
