Israel's Beresheet Moon Mission

The first privately financed mission to the Moon has lifted off from Cape Canaveral in Florida.
The Israeli robot was put on a path to the lunar body by a Falcon rocket - a trip that will take two months.
Beresheet, as it's known, will try to land on the lunar surface, take some pictures and conduct some experiments.
Only government space agencies from the US, Russia and China have previously managed soft touchdowns.

ISRO Set to Launch First 3 Orbit Mission

Indian Space Research Organisation (ISRO) is all set to launch PSLV-C45 in March which will put 30 satellites in three different orbits. The PSLV-C45 will also carry a satellite for electronic intelligence.
Sivan said that the launch of Chandrayaan-2, India's second moon mission, the Bengaluru-based space institute is set to launch the mission by April end.
Sivan also talked about the Small Satellite Launch Vehicle (SSLV), which will launch two 'strategic purpose' satellites in July-August this year.
SSLV is a small satellite launcher. The first launch will take place in July-August where two small satellites will be launched. They are for a strategic purpose and will be used for monitoring and mapping.

India to Have Own DNS

The government will soon roll out a public Domain Name Server, or DNS, for India aimed at providing a faster and more secure browsing experience for Internet users in the country, while ensuring that citizens' data is stored locally.
A DNS is a like a directory for the Internet.
It helps to convert domain names that are easy for people to remember into IP addresses, which are used by computers/machines to communicate.
If the DNS is either slow or fails to work, users will not be able to locate web addresses.
As per the government, the main aim of bringing our own public DNS is to ensure availability, particularly for smaller Interest Service Providers (ISPs) who don't have credible DNS. Bigger ones usually have their own DNS.

Israel Set to Join Elite Lunar Club

Israel`s first spacecraft built to land on the moon was set for launch from Florida on a mission that, if successful, would make the Jewish state only the fourth nation to achieve a controlled touchdown on the lunar surface.
The unmanned robotic lander dubbed Beresheet - Hebrew for the biblical phrase "in the beginning" - was due for liftoff atop a Falcon 9 rocket launched by California-based entrepreneur Elon Musk`s SpaceX company from Cape Canaveral Air Force Station.
If all goes according to plan, Beresheet, about the size of a dishwasher, will arrive on the near-side of the moon in mid-April following a two-month journey through 4 million miles (6.5 million km) of space.
A flight path directly from the Earth to the moon would cover roughly 240,000 miles (386,242 km).

Hayabusa-2 Touches Down on Asteroid

A Japanese spacecraft touched down on an asteroid in an attempt to collect a sample of rock from the surface.
The Hayabusa-2 probe was trying to grab the sample from a pre-chosen site on the asteroid Ryugu.
The spacecraft reached asteroid Ryugu in June 2018 after a three-and-a-half-year journey from Earth.
It is expected to return to Earth with the rocky material it has grabbed in 2020.
Ryugu belongs to a particularly primitive type of space rock known as a C-type. The near-Earth asteroid (NEA) is a relic left over from the early days of our Solar System.

Gene-edited Animal Plan

A researcher in Edinburgh is leading efforts to develop gene-edited farm animals for poor farmers in Africa.
Prof. Appolinaire Djikeng is developing cows, pigs and chickens that are resistant to diseases and more productive.
Among them are cattle that have been gene edited to be heat-resistant.
Details of the project were given at the American Association for the Advancement of Science meeting in Washington DC.
Prof. Djikeng is the director of the Centre for Tropical Livestock Genetics and Health.

NASA's InSight Mission

The US space agency's (NASA) InSight mission has positioned the second of its surface instruments on Mars.
Known as HP3, the heat-flow probe was picked up off the deck of the lander with a robot arm and placed next to the SEIS seismometer package, which was deployed in December.
Together with an onboard radio experiment, these sensor systems will be used to investigate the interior of the planet, to understand its present-day activity and how the sub-surface rocks are layered.

NASA Bids Adieu to Opportunity

Opportunity, a remarkably durable NASA rover designed to roll along the surface of Mars for three months, has stopped communicating with Earth after 15 years of service, ending a mission that astounded the US space agency.
Engineers lost contact with the solar-powered vehicle on June 10 during a dust storm that encircled Mars. Since then, NASA officials made numerous attempts to reach the six-wheeled rover.
Opportunity landed on Mars in January 2004.
