5-foot-diameter heat shield will be integrated onto a high-fidelity Orion mockup later this year and undergo water-impact tests at Langley's Hydro Impact Basin next spring.
Images taken by the HiRISE camera on NASA's Mars Reconnaissance Orbiter, or MRO, and initially searched by Michael Croon of Trier, Germany, a former member of the European Space Agency's Mars Express operations team, have identified clear evidence for the lander and convincing evidence for key entry and descent components on the surface of Mars within the expected landing area of Isidis Planitia, an impact basin close to the equator, The Guardian reported.

If this theory had been correct, the basin it formed would be the largest asteroid impact basin on the moon.
Published in the journal Science, the findings of a team of researchers from Nasa's Mars Science Laboratory Curiosity rover mission found that the Gale Crater, a 150km-wide impact basin with a mountain in the centre, had at least one lake 3.
Ten months ago the rover landed inside a giant impact basin near the planet's equator, a site selected because of the 3-mile-high (5-km-high) mound of layered rock rising from the crater floor.
The Hydro Impact Basin is 115 feet long, 90 feet wide and 20 feet deep (35 x 27 x 6 meters).
Crater floors are tilted in some areas, and the floor of the Caloris impact basin rises above the rim in some places.
The mascon gravity anomaly in Figure 6 consists of the well-defined relatively positive 26 mGal anomaly overlying the inferred impact basin.
While Mars Express fires its main engine to go into Martian orbit, Beagle 2 will head for a landing site within a large impact basin near the planet's equator.
It is thought the broken-up nature of Nili Fossae may be linked to the Isidis impact basin, formed long ago by an asteroid or comet.
This is very ancient terrain that preserves the remnants of a giant impact basin in the form of a system of subdued, parallel, curving ridges about six miles wide, 300 feet high, and spaced about 30 miles apart.
