Here comes the Sun: New spacecraft to fly closer than ever before

Solar Probe Plus

On August 11, LASP research scientist, David Malaspina, will have a front-row seat for the launch of NASA’s newest mission, the Parker Solar Probe.

The event, which is scheduled to take place at Cape Canaveral Air Force Station in Florida, will be a must-see for scientists who have spent their careers watching the Sun. Over its seven-year mission, the Parker Solar Probe will fly closer to our home star than any spacecraft in history, dipping to within four million miles of the surface and grazing the Sun’s outer atmosphere, or corona.

MAVEN Mission Reveals Speed of Solar Wind Stripping Martian Atmosphere

Scientists involved in NASA’s Mars Atmosphere and Volatile Evolution (MAVEN) mission, which is being led by the LASP team at the University of Colorado Boulder, have identified the process that appears to have played a key role in the transition of the Martian climate from an early, warm and wet environment that might have supported surface life to the cold, arid planet Mars is today.

MAVEN data have enabled researchers to determine the rate at which the Martian atmosphere currently is losing gas to space via stripping by the solar wind. The findings reveal that the erosion of Mars’ atmosphere increases significantly during solar storms. The scientific results from the mission appear in the Nov. 5 issues of the journals Science and Geophysical Research Letters.

MAVEN spacecraft detects aurora and mysterious dust cloud around Mars

NASA’s Mars Atmosphere and Volatile Evolution (MAVEN) spacecraft has observed two unexpected phenomena in the Martian atmosphere: an unexplained high-altitude dust cloud and aurora that reaches deep into the Martian atmosphere.

The presence of dust at orbital altitudes from about 93 miles (150 kilometers) to 190 miles (300 kilometers) above the surface was not predicted. Although the source and composition of the dust are unknown, there is no hazard to MAVEN and other spacecraft orbiting Mars.

CU-Boulder students to help control instruments on MMS from LASP

LASP will serve as the Science Operations Center for a NASA mission launching this month to better understand the physical processes of geomagnetic storms, solar flares and other energetic phenomena throughout the universe.

The $1.1 billion Magnetospheric Multiscale (MMS) mission will be comprised of four identical, octagonal spacecraft flying in a pyramid formation, each carrying 25 instruments. The goal is to study in detail magnetic reconnection, the primary process by which energy is transferred from the solar wind to Earth’s protective magnetic space environment known as the magnetosphere, said LASP Director Daniel Baker, Science Operations Center (SOC) lead scientist for MMS.

LASP scientists instrumental in mission to Jupiter

Several LASP scientists are involved in NASA’s upcoming Juno mission to Jupiter. Scheduled to launch on August 5, 2011, the mission will improve understanding of our solar system origins by revealing details about the formation and evolution of the gas giant. The spacecraft will embark on a five-year, 400-million-mile voyage to Jupiter, where it will orbit the planet 33 times, collecting data for more than one Earth year.

PRESS RELEASE: LASP-led mission to Mars achieves major milestone

The CU/LASP-led mission to Mars, devoted to understanding the Martian upper atmosphere, reached a major milestone last week when it successfully completed its Mission Critical Design Review (CDR) at NASA’s Goddard Space Flight Center in Greenbelt, Maryland. An independent review board, comprised of reviewers from NASA and several external organizations, met from July 11-15 to validate the system design of the Mars Atmosphere and Volatile Evolution, or MAVEN, mission.
