Sounding Rocket Launches CHESS Mission to Study the Matter Between Stars

The Colorado High-resolution Echelle Stellar Spectrograph, or CHESS 4, was successfully launched on a NASA Black Brant IX sounding rocket at 12:47 p.m. EDT, April 16 (4:47 a.m. local, April 17) from the Kwajalein Atoll in The Republic of the Marshall Islands.

The CHESS 4 mission will study the interstellar me­dium, the matter between stars. The mission focuses on translucent clouds of gas, that provide the fundamental building blocks for stars and planets. These clouds have very low densities and the only way to study them is to measure how a cloud is affected by a star -- and its associated outpouring of stellar material, the stellar wind -- moving through it.

The payload systems reported a nominal flight, proceeding as expected. The payload is to be recovered, making it the second NASA astronomical mission with water recovery. Hampered by high winds since the targeted launch day of April 13, the CHESS 4 left the pad with only 13 minutes left on the last day of the launch window.

The CHESS 4 instrument was developed by the Laboratory for Atmospheric and Space Physics at the University of Colorado, Boulder. The mission was preceded by the launch of the Penn State Water Recovery X-ray (WRX) rocket experiment on April 4. The successful launch of both missions brings to an end this year’s Kwajalein campaign.

Following a successful launch of Maxus 9 the largest European sounding rocket with scientific micro gravity experiments, Airbus is providing a stunning 360° view from space. The spacecraft, launched from the Esrange Space Center in Kiruna, Sweden, was equipped by Airbus with support from their joint venture partner Swedish Space Corporation in order to provide unique 360° footage of the launch from the rocket perspective. Viewers can see spectacular images of the take-off, down to Lapland getting smaller while the rocket soars into the sky, then spectacular views of the Planet and Space once the sounding rocket goes through the atmosphere and reaches its highest altitude of 700km, before the payload falls free back down to earth, and completes its’ parachute-assisted touchdown. The Maxus programme is a joint venture between Swedish Space Corporation and Airbus, providing access to microgravity for ESA-contracted experiments. Sounding rockets are important to the scientific community as they offer research institutes a one-stop lab in which they can perform micro-gravity experiments. Technicians receive data and can adjust parameters thanks to real-time transmission to ground stations throughout the free fall time. Being able to launch, monitor and retrieve experiments in one day enables researchers to analyze their results almost immediately.

World’s smallest orbital rocket fails on experimental launch. A Japanese technology demonstration mission ended in failure Sunday morning after what was hoped would be the smallest orbital-class rocket to loft a payload into space. Developed by the Japanese Aerospace Exploration Agency, the SS-520-4 rocket lifted off at 8:33am Japan Standard Time from the Uchinoura launch base in Kagoshima Prefecture. However, telemetry was lost 20 seconds into the flight. Visual clues indicated that both stages separated on time, but its theorized the second stage shutdown soon after igniting. 

Due to the size of the rocket, no telemetry equipment was installed on the vehicle’s second stage, so the condition of the rocket and its systems during ascent was unknown. JAXA reported that the vehicle fell into the Pacific ocean at the impact zone for the first stage 150 kilometers downrange.

Had launch been successful, the SS-520-4 would have been the smallest rocket currently active in the world to send a payload into orbit. The rocket measures 31 feet tall and just 1.7 feet in diameter. All three of the rocket’s stages use solid propellant. JAXA modified the SS-520 sounding rocket for orbital missions in an attempt to prove technological readiness towards launching cubesats.  Currently, cubesats must ride as secondary payloads for larger satellites on larger vehicles.Satellites often wait years for a ride into space, and have no control over the rocket’s orbital parameters. By having a dedicated launch vehicle, operators of cubesats are able to access space quicker and cheaper. In America, companies such as NanoRacks offer customized cubesats that are delivered to the International Space Station for deployment. Other companies such as Rocket Lab are developing their own small launch vehicles for commercial use.

On January 26th just after midnight the University of Alaska, Fairbanks launched 4 sounding rockets to study the interaction of solar winds and Earth’s atmosphere. Using different gasses they were able to make a glowing cloud of sorts that would allow them to study this interaction with imagery.
