Here’s what happens. NASA also released a GIF of the various surveys Osiris-Rex carried out after arriving at Bennu in early December The series of images, captured between Nov. 30 and Dec. 31, helped the team more accurately determine Bennu’s mass, which ensured that the orbital insertion would proceed smoothly. You can see the GIF, captured by Osiris-Rex’s black-and-white NavCam, below:Enlarge ImageOsiris-Rex surveyed 101955 Bennu before slipping into orbit on December 31.  NASA/Goddard/University of Arizona/Lockheed Martin Space The orbital period, lasting until mid-February, is expected to provide additional details about Bennu’s gravity, orientation and spin, along with a better understanding of its mass. All those observations should lead to completing one of the chief objectives for Osiris-Rex: retrieve a sample from Bennu’s surface and fly it back to Earth. In 2020, the spacecraft will extend a specially designed arm, called Tagsam, for a brief high-five with the asteroid. The arm will blow nitrogen gas onto the surface of Bennu, kicking up handfuls of dirt, which the spacecraft will fly back to Earth in 2023.A successful pickpocketing will give scientists a more detailed look at the kind of compounds that make up the potentially hazardous object.Bennu is the near-Earth object that’s second most likely to collide with our planet, only outranked by an asteroid known as 1950 DA on NASA’s Palermo Technical Impact Hazard Scale. Though they’re ranked as hazardous, the actual likelihood they would ever collide with Earth is incredibly low — Bennu could smack into Earth between 2169 and 2199. 1950 DA shouldn’t trouble you at all. If it were to hit, that impact wouldn’t occur until 2880. Sci-Techcenter_img Comments Now playing: Watch this: 2 Fly, Osiris-Rex! Fly! NASA/Goddard Visiting a distant, icy world that looks like a snowman certainly had space enthusiasts enraptured in the first days of 2019, but some other historic NASA news slipped through in the final hours of 2018 — and it might reveal just as much about our solar system.The asteroid-chasing Osiris-Rex (Origins, Spectral Interpretation, Resource Identification, Security, Regolith Explorer) performed its own historic maneuver on New Year’s Eve. An eight-second thruster burn on Dec. 31 placed the spacecraft in orbit around 101955 Bennu, which drifts through the solar system’s asteroid belt between the Earth and Mars.By inserting itself into orbit around Bennu, Osiris-Rex will survey the asteroid from a distance of only about 1 mile (1.75 kilometers) from its center. Bennu’s small size creates an incredibly tiny gravitational force, so maintaining that orbit will require lots of little adjustments, made by NASA and its collaborating organizations. “The gravity of Bennu is so small, forces like solar radiation and thermal pressure from Bennu’s surface become much more relevant and can push the spacecraft around in its orbit much more than if it were orbiting around Earth or Mars, where gravity is by far the most dominant force,” said Dan Wibben, maneuver and trajectory design lead.

Market cracks as RBI fails to go beyond the expected 25 bps

first_imgA road sign is seen next to the Bombay Stock Exchange (BSE) building in Mumbai. The market that priced in the expectation of a 25 bps repo rate cut cracked after RBI failed to beat the expectations.REUTERS/Danish SiddiquiThe Reserve Bank of India’s (RBI) third successive 25 basis points (bps) cut bringing the repo rates to the lowest in nine years at 5.75 per cent failed to enthuse the market as the bench market indices plunged, erasing last week’s gains. RBI Governor Shaktikanta Das’ announcement of the Monetary Policy Committee (MPC) decision to change its policy stance to ‘accommodative’ from ‘neutral’, effectively removing rate rises in immediate future, also did not help the market sentiment.National Stock Exchange (NSE) benchmark Nifty shed about 178 points or 1.48 per cent to close around 11,843 points on Thursday. Of the 50 scrips that make up the benchmark, 37 shares declined while only 13 advanced and the index has fallen below the 50-day moving average, showing the market’s overall disaffection. Bombay Stock Exchange (BSE) index Sensex lost about 553 points or 1.38 per cent to close at 39,529 points.The market had priced in the 25 bps rate cut after the latest numbers showed a decelerating economy with the GDP growth pegged at 6.7 per cent. Among the top gainers were retail and FMCG stocks like Titan and Hindustan Unilever Limited (HUL) and energy stocks like Coal India Limited and National Power Grid Corporation. Banking stocks including State Bank of India (SBI), IndusInd Bank and Yes Bank along with GAIL and India Bull Housing topped the declining bunch.Sovereign bonds rallied, sending benchmark yields to their lowest since November 2017, according to a report on Livemint website. The rupee also strengthened against the dollar. Pedestrians walk on Dalal Street next to the Bombay Stock Exchange (BSE). Once the street’s expectations were met by the RBI Monetary Policy Committee, profit-taking set in putting pressure on the indices.INDRANIL MUKHERJEE/AFP/Getty ImagesBanks and realty stocks were expected to be top beneficiaries of a rate cut because the expected fall in interest rates would bring them more business boosting revenue and profits. Nifty’s sectoral indices, however, declined across the board, with Nifty Bank declined 2.32 per cent. PSU Bank Index suffered worst with 4.3 per cent fall while Private Bank index declined 2.29 per cent.”Low inflation and subdued growth are the drivers of the move. Yet, the real concern is the lack of transmission of rate cuts into the effective lending rate. Liquidity conditions also remain tight for a large part of the corporate sector. Effective transmission and adequate liquidity remain key challenges,” the report quoted Sujan Hajra of Anand Rathi Shares & Stock Brokers as saying.last_img read more

HC asks DU not to treat law centre in stepmotherly way

first_imgThe Delhi High Court on Wednesday asked the Delhi University not to treat its the three law colleges, which have been in controversy recently for alleged non-compliance of the Bar Council Of India (BCI) norms, in a “step-motherly” way.A bench of Chief Justice G Rohini and Justice Rajiv Sahai Endlaw said that the Delhi University’s (DU) law schools are very much part of the varsity and closing down will affect the future of the students. “The three law centres are very much part of the DU,” the court said, adding that they should not be treated in a a step-motherly way. The court said this when it was informed that the BCI inspection committee that had visited and reported on the state of affairs was of the firm view that the DU’s three law schools should be closed down. The inspection committee has recommended that the DU’s law centres failed to comply with 17 conditions listed and it should not be allowed to admit new batches of students. The court was hearing a PIL filed by Tarun Narang seeking setting aside of a notification barring fresh law graduates of the DU from being enrolled as lawyers.last_img read more

St Xaviers College Raghabpur campus to come up with hostels

first_imgKolkata: St. Xavier’s College (Autonomous) is taking a slew of measures for academic expansion and infrastructure development and also setting up hostels for boys and girls on its Raghabpur campus in South 24-Parganas to cater to the students from the far-flung rural areas of the Sunderbans.”We have found out that currently only students within a 15 km radius attend the college at Raghabpur, whose medium of instruction is Bengali. Hence, we have planned to set up two hostels – one each for boys and girls so that students from the interiors of Sunderbans can have access to higher education. The hostel fees will be nominal to ensure that they face no difficulty in staying in the hostels and pursue their studies,” Rev Dr Dominic Savio, principal of St. Xavier’s College said. Also Read – Heavy rain hits traffic, flightsIt may be mentioned that the Raghabpur campus, which started five years back, has been doing very well and the college intends to impart some soft skill development programmes and vocational training programmes to make them industry friendly. The college also intends to set up a community college on this campus.”We will start post graduate courses in English, Political Science or International Relations and Education on its Park Street campus and in Bengali on Raghabpur campus from the academic year 2019-20. The College also has plans to start PG course in Chemistry,” Savio said. The college also has plans to offer PhD in the subjects that will be introduced from the next academic year.
