Comparing a magnified image of the blob (top right) with a model of the craft as it was supposed to deploy (bottom right) suggests that two of its solar panels failed to open, covering the antenna in the central disc (the probe's opened lid) that was meant to keep it in contact with Mars Express, its European mother ship.
As it punches into the Martian sky at 21,000 km (13039 miles) per hour, the disc-shaped probe will endure temperatures of more than 1500C 2732FF).
The pulsed beam excites the phase-change material (here a Si/ZnS-SiO2 310 Si/ZnS-SiO2 31020 nm)/Ge2Sb2Te5(30 nm) sample typical of that used in optical storage discs) while the probe beam measures the reflectivity.
An alien sitting down to play the gold disc on the Voyager probe would likely feel much as I do when watching an episode of Simon Cowell's The X Factor.

Kambin [ 20] reported the first results of arthroscopic discectomy by using a cannula and forceps, which was later refined by Maroon and Onik [ 25] using a guillotine-like probe into the disc.
These devices consist of a probe with tip or disc, which is applied perpendicular to the skin in gradual increasing force to produce noxious stimulus.
(A – D ) RNA in situ hybridization with dpp (A and B ) or gbb (C and D ) probe for wild type wing discs (A, C ) or wing discs expressing UAS-Dpp (B ) or UAS-Gbb (D ) with wing disc specific Gal4 driver MS1096.
Here, we report design and fabrication of an apparatus that allows Seebeck measurement by 2-probe method concurrently with electrical resistivity by 4-probe method of bar and disc samples in the temperature range from 300 to 1000 K.
