In a momentous leap for Indian lunar exploration, the Chandrayaan-3 lander, Vikram, has accomplished a remarkable feat on the surface of the Moon. The lander successfully executed a hop, a controlled jump, which could pave the way for crucial insights for upcoming missions with aspirations of returning lunar samples.
Vikram Lander Exceeds Expectations
Isro, the Indian Space Research Organisation, joyfully reported, “Vikram Lander exceeded its mission objectives. It successfully underwent a hop experiment. On command, it fired the engines, elevated itself by about 40cm as expected and landed safely at a distance of 30โ40cm away.”
The experiment showcased the robustness of Vikram’s systems as it responded flawlessly to commands. All systems performed nominally, and the payloads onboard, including Ramp, ChaSTE, and ILSA, were smoothly retracted and deployed as planned during and after the experiment.
Sleep Mode Initiated
While Isro did not specify the exact time of this extraordinary experiment, it is believed to have taken place before Vikram and its companion, the rover Pragyan, were put into sleep mode. Isro anticipates reactivating them on September 22 when the lunar day dawns once more.
A Wealth of Lunar Discoveries
In the period spanning from August 23 to Saturday, both Pragyan and Vikram have been busy sending back a treasure trove of scientific data. Some of this data has already been made accessible to the public by Isro.
Pragyan’s instruments, the Laser-Induced Breakdown Spectroscope (LIBS) and Alpha Particle X-ray Spectroscope (APXS), have made significant discoveries, confirming the presence of sulfur on the lunar surface. Meanwhile, Vikram’s Chandra’s Surface Thermophysical Experiment (ChaSTE) has diligently recorded the temperature profile of the lunar topsoil in the vicinity of the pole.
Mysterious Lunar Events
Intriguingly, Vikram’s Instrument for the Lunar Seismic Activity (ILSA) detected a “natural event” on August 26. The source of this lunar event is yet to be confirmed by Isro. Additionally, Vikramโs RAMBHA payload has transmitted valuable data.
Sulfur and Lunar Volcanism
Speaking about the significance of the discovery of sulfur, Isro chairman S. Somanath explained, “Of course, sulfur is a volcanic material. Its availability is high, and it has some utility, as some earlier research hypotheses have shown. “
However, he cautioned that the data collected so far is primarily measurement data, and no immediate conclusive statements can be made. Somanath stated, “We have only made initial assessments so far. The principal investigators will work with the data, use models, and make predictions. Some scientific papers on this topic have already reached me, but I am yet to review them. “
Isro’s Chandrayaan-3 mission continues to surprise and excite with its significant findings and successful experiments. The discovery of sulfur and Vikram’s safe hop bring India one step closer to unraveling the Moon’s mysteries and preparing for ambitious lunar missions in the future.
