NASA is going to name next Mars rover in 2019

The Mars 2020 rover mission addresses high-priority science goals for Mars, including key questions about the potential for life on the Red Planet.

 NASA is looking out for a partner to conduct a contest among student to name the agency's next rover to the Red Planet the Mars 2020 mission in the 2019 academic year.

The Mars 2020 rover mission addresses high-priority science goal for Mars, including a key question about the potential for life on the Red Planet.

Corporation,  nonprofits and educational organizations interested in sponsoring the contest can send proposals to NASA.

We've been doing naming contests since the very first Mars rover back 1997, said Thomas Zurbuchen, Associate Administrator for the Science Mission Directorate at NASA Headquarters, in Washington.

"Thousands of kids participate, and  their enthusiasm for the contest and Mars is an infection," Zurbuchen said

The selected partner will have an opportunity to part of a historic mission, NASA said.

Mars 2020 is targeted for launch in July or August 2020 form the Cape Canaveral Air Force Station in Florida.

NASA Satellite send the first Image of sun

Parker Solar Probe (previously Solar Probe, Solar Probe Plus, or Solar Probe+, abbreviated PSP) is a NASA robotic spacecraft route to probe the outer corona of the Sun. It will approach to within 8.86 solar radii (6.2 million kilometers) from the photosphere of the Sun and will travel, at closest approach, as fast as 700,000 km/h.

Just over a month into its seven-year mission to touch the sun, NASA's Parker solar Probe has beamed back the first-light data from each of its four instrument suites, the US space agency said.

On September 9, Wide-field Image for Soler Probe's (WISPR) -- the only image on the probe-door was opened, allowing the instrument to take the first image during its journey to the sun.

WISPR with both its inner and outer telescope snapped a blue-toned, two-panel image of space with stars visible throughout.

while the Sun is not visible in the image, it showed Jupiter.

Launched on August 12, Parker Solar Probe, NASA's historic small car-sized probe will journey steadily closed to the Sun, until it makes its closed approach at 3.8 million miles.

The Parker Soler Probe's first close approach to the Sun will be in November.

Launch occurred on August 12, 2018, at 3:31 a.m. EDT, 7:31 a.m. GMT. The spacecraft is operating nominally, and during its first week in space, it deployed its high-gain antenna, magnetometer boom, and its electric field antennas. The spacecraft performed its first scheduled trajectory correction on 20 August 2018, while it was 5.5 million miles from Earth, and traveling at 63,569 km/h (39,500 mph).

Instrument testing will begin in early September, and its first science observations will be transmitted in December 2018.

Uber Will going to do billion-dollar food delivery startup : Deliveroo

The U.S. based ride-bailing startup uber is side to be in talk to buy  U.K - based billion-dollar food delivery startup deliveroo, according to reports. The value of the deal is not yet known.
It was founded in 2013 by WILL SHU, raised over $300 million.
London-based Deliveroo was last year value at more than $2 billion after raising $98 million from private investors.

Uber Chief Executive Officer Dara Khosrowshahi has made the company’s food-delivery business a top priority ahead of a planned initial public offering in the second half of 2019. The San Francisco-based company is weighing other acquisitions, too. It’s in talks with Middle Eastern ride-sharing rival Careem, people familiar with the matter have said. After selling its ride-hailing businesses in Southeast Asia, China and Russia, Uber is eager to buy competitors, rather than sell its remaining local businesses.

Deliveroo is one of Europe’s biggest startups and last year raised about $480 million from investors including Fidelity Investments and T. Rowe Price Group Inc. The company competes directly with Uber Eats, Uber’s food delivery business.

Deliveroo was in financing talks last year with SoftBank Group Corp., one of Uber’s major investors. The negotiations abruptly ended after SoftBank concentrated on backing Uber.

If it goes through, the acquisition would be the latest example of a European or Middle Eastern startup falling into foreign hands.

Over the past two years, Apple Inc. acquired music-identification service Shazam for about $400 million, despite initial concern from European regulators; Amazon.com Inc. snapped up Dubai-based online retailer Souq.com for $580 million, shocking locals; and Chinese travel giant Ctrip.com International Ltd. agreed to buy Scottish flight-booking site Skyscanner for $1.7 billion.
