On May 7th, 2015 the University of Colorado announced a partnership agreement with the United Arab Emirates on a 2021 Mars Mission.
A mission to study dynamic changes in the atmosphere of Mars over days and seasons led by the United Arab Emirates (UAE) involves the University of Colorado Boulder as the leading U.S. scientific-academic partner.
The complete announcement, including The UAE’s U.S. scientific-academic partners also include the University of California, Berkeley, and Arizona State University, here.
MAVEN and UAE’s Hope mission will provide very powerful combination of Mars science measurements
“The UAE Space Agency has been very consistent in that they don’t want to do a technology demonstration mission,” said Jakosky. “They want to contribute substantively to the world’s exploration and understanding of Mars.”
“The Hope science measurements will make a valuable contribution by themselves,” he added. “And if MAVEN is still operating when #Hope gets there, the combination will be very powerful.”

Marking the end of an era, spacewalkers Andrew Feustel and John Grunsfeld removed the no-longer-needed COSTAR corrective optics package from the Hubble Space Telescope today and replaced it with the Cosmic Origins Spectrograph, an $88 million state-of-the-art instrument designed to study the large-scale structure of the universe.
The Cosmic Origins Spectrograph, comprised two instruments, one of which was developed in conjunction with CASA University of Colorado Boulder and UC Berkeley’s Space Sciences Lab. The detector and electronics package were built here at our lab. The full article on the COS instrument installation is found here.

NASA’s Nuclear Spectroscopic Telescope Array, or NuSTAR, has found evidence that a massive star exploded in a lopsided fashion, sending ejected material flying in one direction and the core of the star in the other.
The findings offer the best proof yet that star explosions of this type, called Type II or core-collapse supernovae, are inherently asymmetrical, a phenomenon that had been difficult to prove before now.

We detected what some might call the X-rays howls of zombie stars! Translation for astronomers: NuSTAR detected a surplus of high-energy X-ray emission in the center of our galaxy, which might be coming from a population of compact, dead stars.
Peering into the heart of the Milky Way galaxy, NASA’s Nuclear Spectroscopic Telescope Array (NuSTAR) has spotted a mysterious glow of high-energy X-rays that, according to scientists, could be the “howls” of dead stars as they feed on stellar companions.
NASA has beefed up a process of traffic monitoring, communication and maneuver planning to ensure that #Mars orbiters do not approach each other too closely.
Last year’s addition of two new spacecraft orbiting Mars brought the census of active Mars orbiters to five, the most ever. MAVEN and ISRO’s Mars Orbiter Mission joined the 2003 Mars Express from the ESA – European Space Agency and two from NASA: the 2001 Mars Odyssey and the 2006 Mars Reconnaissance Orbiter (MRO). The newly enhanced collision-avoidance process also tracks the approximate location of NASA’s Mars Global Surveyor, a 1997 orbiter that is no longer working.
It’s not just the total number that matters, but also the types of orbits missions use for achieving their science goals. #MAVEN, which reached Mars on Sept. 21, 2014, studies the upper atmosphere. It flies an elongated orbit, sometimes farther from Mars than NASA’s other orbiters and sometimes closer to Mars, so it crosses altitudes occupied by those orbiters. For safety, NASA also monitors positions of ESA’s and India’s orbiters, which both fly elongated orbits.

MAVEN’s primary mission includes five 5-day “deep-dip” campaigns, in which the periapsis (lowest point in the orbit) is lowered from about 93 miles (150 km) to about 77 miles (125 km). The current campaign is scheduled to coincide with the periapsis of the spacecraft crossing Mars’ equator into the southern hemisphere for the first time.
At an altitude of 77 miles (125 km), Mars’ atmosphere is around 30 times more dense than it is at MAVEN’s nominal science mapping periapsis of 93 miles (150 km). To accommodate for the increase in atmospheric density, the spacecraft’s solar panels are bent at a 20° angle, which shifts the center of air pressure away from the center of gravity, providing self-stabilization.
The “deep dip” campaigns will provide data from the boundary where Mars’ upper and lower atmospheres meet—also referred to as the “homopause”—enabling the spacecraft to sample the entire upper atmosphere of Mars.
The aircraft that air-launches the Pegasus rocket has been repainted with new livery to mark the recent corporate merge that formed Orbital ATK.
The L-1011 jet, named Stargazer, carries the light-class Pegasus launchers to an altitude of 39,000 feet and releases the booster to fire into space.
Pegasus has flown 42 times and the 32 using the XL version. The rocket weighs 51,000 pounds, stretches 55 feet long and is comprised of three solid-fueled stages for boosting small satellites into orbit. Launches have occurred from California, Virginia, Florida, the Canary Islands and the Kwajalein Atoll in the Marshall Islands.
Stargazer was delivered to Air Canada in March 1974. It was purchased by Orbital ATK in 1992 and modified as the Pegasus launch platform.With the push of a button in the Stargazer’s cockpit by the co-pilot, the rocket is cast free to fall for five seconds, dropping 300 feet below the aircraft while traveling at Mach 0.82. During the plunge, the onboard flight computer will sense the rocket’s separation from the carrier jet and issues a command to release the safety inhibits in preparation for ignition.
The first stage solid-fueled motor of Pegasus is lit at T+plus 5 seconds to begin the powered journey to orbit. The rocket’s heritage includes deploying over 70 satellites since 1990 for NASA, commercial customers and the U.S. military.
Pegasus celebrated the 25th anniversary of its maiden launch on April 5.
Two more Pegasus flights are on the NASA manifest for 2016 and 2017. The first will launch eight Cyclone Global Navigation Satellite System, or CYGNSS, spacecraft into orbit from Florida and the second will carry the Ionospheric Connection Explorer, or ICON, to space from the Marshall Islands.
Join us for Cal Day, Saturday, April 18th, from 11am-5pm, the one day each year that UC Berkeley’s Space Sciences Lab opens its doors to the public. Shuttles will be transporting the public every 15 minutes from Hearst Mining Circle on campus to SSL. Activities include walking tours of UC Berkeley’s cutting-edge space science research lab, as well as talks on topics such as space weather, teens doing art-science mashups, a career panel on cool jobs in space science, and hands-on activities for all ages! Get your Science@Cal Passports here, with activities for children 5 and up.
