The Indian Space Research Organisation (ISRO) is continuing its attempt to reach out to India’s moon lander sending communication signals with its Deep Space Network (DSN), said officials.

It is also reported the American space agency National Aeronautics and Space Administration’s (NASA) Jet Propulsion Laboratory (JPL) is sending radio signals to Vikram.

“Attempts are being made to reestablish communication links with the moon lander Vikram. The attempts will be made till September 20-21 when the sunlight will be there in the area where the Vikram has landed,” an ISRO official preferring anonymity told IANS.

The ISRO is trying to establish link with Vikram with its Indian Deep Space Network (IDSN) at Byalalu near Bengaluru.

Scott Tilley, an amateur astronomer who found American weather satellite IMAGE in 2018 that was considered to be lost, on September 10, tweeted: “#DSN 24 beams 12KW of RF at the #Moon in hopes of stimulating #Chandrayaan2’s lander #VikramLander into communicating with home.

“Here’s a eerie recording of the searcher’s signal reflected off the Moon and back to Earth via EME (Earth Moon Earth) on 2103.7MHz.”

“Meanwhile the DSN24 continues emitting its beacon in hopes #VikramLander will respond…A Good Night all!” he said in a recent tweet.

2 Big Asteroids Flying by Earth Pose no Risk: NASA

At the start of 2019, the number of discovered NEOs totaled more than 19,000, and it has since surpassed 20,000. An average of 30 new discoveries are added each week, NASA said

NASA has ruled that the pair of asteroids flying by Earth this weekend could pose a threat to our planet.

“These asteroids have been well observed – once since 2000 and the other since 2010 – and their orbits are very well known,” said NASA’s Planetary Defence Officer Lindley Johnson.

“Both of these asteroids are passing at about 14 lunar distances from the Earth, or about 3.5 million miles away, but small asteroids pass by Earth this close all the time,” Johnson said.

Near-Earth asteroid 2010 C01, estimated to be 120 to 260 metres in size, safely passed Earth at 3.42 a.m. on Saturday. The second object, 2000 QW7 is estimated to be 290 to 650 metres in size will pass later at 11.54 p.m. on Saturday.

Near-Earth objects (NEOs) are asteroids and comets that orbit the Sun, but their orbits bring them into Earth’s neighborhood – within 30 million miles of Earth’s orbit.

These objects are relatively unchanged remnant debris from the solar system’s formation some 4.6 billion years ago.

Most of the rocky asteroids originally formed in the warmer inner solar system between the orbits of Mars and Jupiter, while comets, composed mostly of water ice with embedded dust particles, formed in the cold outer solar system.
