Its payload is the Parker Solar Probe which will swoop to within 4 million miles (5.9 million kilometers) to the Sun’s photosphere, typically considered as the ‘surface’ of the Sun. It will face heat and radiation like no other spacecraft before it. It will provide new data on solar activity and make critical contributions to our ability to forecast major space-weather events that impact life on Earth. Its mission will last approximately 7 years. (See News below)
At 11:00pm on the 31st, Neptune is 7½ degrees to the upper right of the Moon, which is 1 degree above the horizon in the east.
On the 31st the asteroid Vesta is just 2¼ degrees above the 4th magnitude star named '85340' in the constellation of Ophiuchus. For further information please see 'Asteroids' and 'Constellations' in the website above.
By the end of the month Comet 66P Du Toit will be in the constellation of Cetus. Its at its closest to us between the 3rd - 11th August when its 0.917AU distance. It was at 10.2 Magnitude (22/5) For further information please see 'Comets' and 'Constellations' in the website above.
* = Dates and times are subject to change
News: The Parker Solar Probe systems are designed to endure the extreme radiation and heat near the Sun, where the incident solar intensity is approximately 520 times the intensity at Earth orbit, by the use of a solar shadow-shield. The solar shield is 11.4 cm (4½ inches) thick and is made of reinforced carbon-carbon composite,which is designed to withstand temperatures of about 1,377 degrees Celsius. The shield is hexagonal and is mounted at the Sun-facing side of the spacecraft. It's trajectory from Earth will include seven Venus flybys over nearly seven years to gradually shrink its elliptical orbit around the Sun, for a total of 24 orbits. The science phase will take place during those 7 years, focusing on the periods when the spacecraft is closest to the Sun.
Fact: When the Radcliffe Observatory was founded near Pretoria, after the war, local roads were named after stars: Rigel Road, Arcturus Road, Sirius Road,and so on. One of these was named Canopsus Road. Jack Bennett, a well-known amateur astronomer who lived there , wrote to the city council and gently pointed out that it really should be 'Canopus',not Canopsus. Their reply was worth putting on record: 'Thank you for your letter. Unfortunately our maps have now been printed and distributed, and it is not possible to alter the name of the road. Can you not alter the name of the star? The maps of today now show it the right way.

Fact: John Watts Young (b.1930) enjoyed the longest career of any astronaut. He became the first person to make six space flights over the course of 42 years and is the only person to have piloted, and been commander of four different classes of spacecraft: Gemini, the Apollo Command/Service Module, the Apollo Lunar Module and the Space Shuttle.
News: On April 5th it was announced that a “Luxury Space Hotel” will be launched into space. Space tourists will have a new orbital destination four years from now, if one company's plans come to fruition. Orion Span aims to launch its “Aurora Station” in late 2021 and begin accommodating guests in 2022. It will be the first affordable luxury space hotel – How much I hear you ask? - Well a 12 day stay aboard the Aurora Station will start from $9.5 million. Anyone interested? Well I am, its just a matter about the cost? Though if (that's a big if) I win the Euromillions I wouldn't think twice – I would just go. I've been 7 miles up in Concorde. At least another 43 miles to go to get into outer space then beyond. (My 12 day mission will be …..to seek out new civilizations and to boldly go where no man as gone before. Well!!! Anybody got some spare cash???) From 2001 – 2009 seven private citizens took a total of eight trips to the International Space Station (ISS) paying an estimated $20 million to $40 million each time.

There is a scheduled launch sometime this month* from Vandenberg Air Force Base in California as part of an Iridium commercial satellite launch on a SpaceX Falcon 9 rocket. GRACE-FO (GRACE Follow-On), a partnership between NASA and the German Research Centre for Geosciences (GFZ), is a successor to the GRACE mission, which tracks Earth's gravity field and water movement.
There is a planned launch this month* from Xichang, China. A Chinese Long March 3B rocket will launch the APStar-6C commercial communications satellite for APT Satellite Company Ltd under an end-to-end contract signed with China Great Wall Industry Corp (CGWIC).
Comet C/2016 N6 Panstarrs will be in the northern constellation of Camelopardalis this month. Its last observable magnitude was 12.5 (Mar 12th) It reaches perihelion this July. For further information please see 'Comets' and 'Constellations' in the website above.
For the first week this month before dawn Comet 24P Schaumasse will be approximately half way between the two bright stars Sabik and Zeta Ophiuchi in the constellation of Ophiuchus. Its last known magnitude was 13 (Mar 12th). For further information please see 'Comets' and 'Constellations' in the website above.
Mercury is at inferior conjunction on the 1st. It also rises no more than 30 minutes before the Sun this month and is unlikely to be seen in the dawn sky unless conditions are very favourable.

Facts: Frank Borman was a hero of the American Space Odyssey. He led the first team of American astronauts to circle the Moon, extending man's horizons into space. He is internationally known as the Commander of the 1968 Apollo 8 mission. A romance with airplanes that began when he was just 15 years old, took Frank Borman to the Air Force then to NASA.
News: Transiting Exoplanet Survey Satellite (TESS) will provide prime targets for further, more detailed characterization with the James Webb Space Telescope (JWST), as well as other large ground-based and space-based telescopes of the future. TESS stars will be 30-100 times brighter than those surveyed by the Kepler satellite. It will comprise the most favorable targets for detailed investigations in the coming decades.
News Extra: For those of us stuck in light polluted areas there is a webcam operated by the Shetland tourist board: Shetland web cams. Cliff Cam 3 looks north from Sumburgh Head. On a clear winters night you may get a good chance to get a glimpse of the Northern Lights or in the coming months view the seabird colonies as they rest on the cliff's edge.

Fact: The Dominion Astrophysical Observatory in Saanich, British Columbia, Canada was completed in 1918. The glass mirror, 73 inches in diameter and 12 inches thick, weighed approximately 4,340lbs and was made by the Saint-Gobain company in Antwerp, Belgium and shipped just a week before the start of World War 1. It was then ground in the United States at the John A Brashear company in Pittsburgh. The mirror had to be reground twice which added 2 years to the completion time of the telescope. The completed mirror was hauled up Little Saanich Mountain by horse and wagon.
News: The satellite Hayabusa 2 which was launched in December 2014 for the asteroid Ryugu is expected to arrive at its target in July this year. It will survey the asteroid for 1½ years, then in December 2019 it will leave for Earth. Operations at the asteroid will be similar to those of the previous Hayabusa, but with an explosive device to dig the surface for fresh sample material to bring back to Earth in 2020.
NASA News: Andrew J Feustal has a Ph.D in the Geological sciences, specializing in Seismology, and is a veteran of two spaceflights. His first was on the final space shuttle mission to the Hubble Space Telescope that improved the observatories capabilities.
Richard R Arnold worked in the marine sciences and as a teacher in places like Morocco, Saudi Arabia and Indonesia. He currently serves as the assistant to the Chief for EVA and Robotics in the Astronaut Office
Oleg Artemyev was born in Riga, present-day Latvia in December 1970 and is married to Malikhova Anna Sergeevna and they have a son. He was involved in developing testing procedures for Extra-vehicular Activity (EVA) equipment in neutral buoyancy at the hydrodynamics laboratory, Yuri Gagarin Cosmonaut Training Centre.

At 6:15pm on the 30th the Moon will be in a straight line with the bright stars Castor and Pollox in Gemini.
A “Total Eclipse of the Moon” occurs on the 31st. Unfortunately it will not be seen here in the UK, Western Europe or South America. At 5:30pm the Full Moon will be 2 degrees above the horizon and due ENE.
By the 31st, Venus sets just 17 minutes after the Sun so its likely to be seen this month until early to mid-February when the planet will become more evident in the evening sky as dusk sets in. It seems a long time since we had some bright planets to view during the evenings.
