At International Meeting, Mission Team Previews the Science of Solar Probe Plus

Posted on 01/05/2017 13:41:46

The science of Solar Probe Plus – NASA’s first mission to “touch” the sun – was on stage last month at the American Geophysical Union’s Fall Meeting in San Francisco. With some 25,000 attendees, representing nearly 100 countries, AGU’s Fall Meeting is the world’s largest Earth and space science conference.

Engineers at the Johns Hopkins University Applied Physics Laboratory in Laurel, Maryland, prepare the developing Solar Probe Plus spacecraft for thermal vacuum tests that simulate conditions in space. Today the spacecraft includes the primary structure and its propulsion system; still to be installed over the next several months are critical systems such as power, communications and thermal protection, as well as science instruments.

NASA's Solar Probe Plus Mission Moves One Step Closer to Launch

NASA's Solar Probe Plus – the first mission that will fly into sun's upper atmosphere and “touch” the sun – has passed a design review, an important milestone leading to its anticipated summer 2018 launch.

NASA Gives Green Light for APL to Begin Building Solar Probe Plus

NASA’s Solar Probe Plus mission - which will fly closer to the Sun than any spacecraft has before- reached a major milestone last month when it successfully completed its Critical Design Review (CDR).

Technicians at the Johns Hopkins University Applied Physics Laboratory in Laurel, Md., prepare an engineering model of the Solar Probe Plus Thermal Protection System, or TPS, for vibration tests in October 2013. The main feature of the TPS is an 8-foot-diameter, 4.5-inch-thick, carbon-carbon, carbon foam shield that will sit atop the Solar Probe Plus spacecraft body. The system will protect Solar Probe Plus from temperatures exceeding 2,500 degrees Fahrenheit and impacts from hypervelocity dust particles as it flies through the sun’s outer atmosphere. The vibration tests simulate the shaking the spacecraft will undergo during launch; Solar Probe Plus is scheduled to launch in 2018.

Solar Probe Plus Moves into Advanced Development

Posted on 03/18/2014 09:26:32

Solar Probe Plus — NASA’s ambitious mission to fly through and examine the sun’s atmosphere — has reached a key stage of development. Solar Probe Plus will begin advanced design, development and testing — a step NASA designates as Phase C — following a successful design review in which an independent assessment board deemed that the mission team, led by the Johns Hopkins University Applied Physics Laboratory (APL) in Laurel, Md., was ready to move ahead with full-scale spacecraft fabrication, assembly, integration and testing.
