Parker Solar Probe Named Popular Science’s 2018 Innovation of the Year

Posted on 11/28/2018 15:00:58

NASA’s Parker Solar Probe – humanity’s first mission to “touch” the Sun – was today named the innovation of the year by Popular Science. The revolutionary spacecraft – designed, built, and operated for NASA by the Johns Hopkins Applied Physics Laboratory in Laurel, Maryland – launched on August 12, 2018.

Parker Solar Probe Reports Good Status After Close Solar Approach

Posted on 11/07/2018 17:13:45

Parker Solar Probe is alive and well after skimming by the Sun at just 15 million miles from our star's surface. This is far closer than any spacecraft has ever gone — the previous record was set by Helios B in 1976 and broken by Parker on Oct.

First perihelion is expected at about 10:28 p.m. EST on Nov. 5. The spacecraft will come within 15 million miles of the Sun's surface and clock in at a top speed of 213,200 miles per hour relative to the Sun — setting new records for both closest solar approach and top heliocentric speed by a spacecraft.

Two days after NASA’s Parker Solar Probe flew past Venus toward its rendezvous with the Sun, the spacecraft had drawn close enough to our star that its power-generating solar array wings began to tilt themselves inward – a task directed by the spacecraft itself, based on the rising temperatures – away from the Sun and behind the sun shield.

The final orbit for the Parker Solar Probe mission uses seven Venus gravity assists to rack up more than 900 hours close to the Sun. The original mission concept, using a single Jupiter gravity assist, got the spacecraft closer to the Sun, but gave scientists less than 100 hours in key areas.

How A Change in Mission Design Unlocked the Journey to the Sun

Posted on 10/04/2018 12:33:27

On Oct. 3, 2018, Parker Solar Probe performed the first significant celestial maneuver of its seven-year mission. As the orbits of the spacecraft and Venus converged toward the same point, Parker Solar Probe slipped in front of the planet, allowing Venus' gravity — relatively small by celestial standards — to twist its path and change its speed.

As NASA’s Parker Solar Probe spacecraft begins its first historic encounter with the sun’s corona in late 2018—flying closer to our star than any other mission in history—a revolutionary cooling system will keep its solar arrays at peak performance, even in extremely hostile conditions.Every instrument and system on board Parker Solar Probe (with the exception of four antennas and a special particle detector) will be hidden from the sun behind a breakthrough thermal protection system (TPS)—an eight-foot diameter shield that the spacecraft uses to defend itself against the intense heat and energy of our star.

NASA’s first mission to go to the sun, the Parker Solar Probe, is named after Eugene Parker who first theorized that the sun constantly sends out a flow of particles and energy called the solar wind.

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.

2016

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 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).

2014

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.
