5 June 2014 South Africa’s 2013 Sevens Player of the Year, Cornal Hendricks, will make his debut for South Africa in the 15-man code next to ten players who started in the Springboks’ final test of 2013 when they face a star-studded World XV at DHL Newlands in Cape Town on Saturday. The speedy Hendricks is the only newcomer in the team as Springbok coach Heyneke Meyer opted for continuity in his team’s first match of the year. The old firm of Bakkies Botha and interim captain Victor Matfield are re-united in the second row. JP Pietersen moves to outside centre. Schalk Burger makes a return to the side for the first time in two-and-a-half years while Frans Steyn, Schalk Brits, Lwazi Mvovo and Johan Goosen are also back after playing no test rugby last year. The five players who started in the 19-10 win over France in Paris last November but are not in the starting team this week, are the injured Jean de Villiers, Jaque Fourie and Eben Etzebeth, as well as Flip van der Merwe and Coenie Oosthuizen, who will both start on the bench.‘Continuity’ “It’s positive to have this kind of continuity in our first start of the year,” said Meyer on Wednesday. “Even though we’ll be starting with a new midfield combination, Frans and JP have both played more than 50 tests for the Boks and with Bryan Habana also in the backline, Cornal will start with a lot of experience around him. “We’re expecting a stern test on Saturday against the World XV and our mindset is to make our nation proud. It should never be anything else when the Springboks play. It will also be a good way to start the season before our first test next week against Wales, but for now we’re only focused on the World XV and playing well.‘Aim’ Looking at the bigger picture, Meyer added: “Our aim for the season is to accelerate and make a step up from 2013. To put ourselves in a position to do that, we simply have to start well.” Of the 23 in action on Saturday, 13 featured in the victory in Paris. One of the new faces is Matfield, who has been named captain with De Villiers out injured during the Castle Lager Incoming Series this month. It will be the 110-time capped lock’s first match in the green and gold since the Rugby World Cup in 2011. Meyer said it was pleasing to see Matfield and Botha re-united, while he was also very excited about the prospects of Hendricks on the wing, Pietersen at outside centre and the return of Burger, Brits and Steyn.‘I wouldn’t have believed it’ “If anyone told me two years ago that Victor and Bakkies would play together again for the Boks, I probably wouldn’t have believed it. They have been great servants of the game in South Africa and now have the opportunity to take it further. “We’re also keen to see what JP can offer at outside centre, where he’s played very well for the Cell C Sharks earlier in his career and for his club in Japan. “Cornal is a player I’ve been following for some time and I thought he made a very good transition from sevens to the 15-man code earlier this year. He’s big and very fast, and hopefully we’ll be able to provide him with some space to attack in. The Springbok Sevens can be very proud of the way in which they aided in his development to a top-class player.‘X-factor’ Meyer also welcomed back two players who he said brought something extra to the Springbok squad: “Frans [Steyn] and Schalk Brits are both special players with the X-factor and it’s wonderful to have them back. Their attitude has been superb and I know they can add a lot in the coming weeks,” he said. “Lwazi has been great for the Cell C Sharks this year and I believe he can make an impact later in the match, while I’ve always rated Johan and it’s good to see him getting back to his best. “This was a tough team selection to make and a couple of players were unlucky to miss out, but I know all of them will keep on pressing hard for selection in the weeks to come. I always like it if players in the team must make it easy for me to leave them in, and players outside the team must make it difficult to leave them out.”SPRINGBOK SQUAD 15 Willie le Roux, 14 Cornal Hendricks, 13 JP Pietersen, 12 Frans Steyn, 11 Bryan Habana, 10 Morne Steyn, 9 Ruan Pienaar, 8 Duane Vermeulen, 7 Francois Louw, 6 Willem Alberts, 5 Victor Matfield (c), 4 Bakkies Botha, 3 Jannie du Plessis, 2 Bismarck du Plessis, 1 Tendai Mtawarira 16 Schalk Brits, 17 Gurthro Steenkamp, 18 Coenie Oosthuizen, 19 Flip van der Merwe, 20 Schalk Burger, 21 Fourie du Preez, 22 Johan Goosen, 23 Lwazi Mvovo SAinfo reporter
The UV environment of the Beagle 2 landing site: detailed investigations and detection of atmospheric state
December 25th 2003 will see the Beagle 2 lander arrive at the surface of Mars in the Isidis region, allowing for the first time in situ measurements of ultraviolet (UV) flux directly from the surface of Mars through the use of a sensor designed as part of a miniaturised environmental package. The expected conditions the sensor will experience are studied here, and the detection signatures for phenomenon such as dust devils. H2O clouds ands near-surface fogs are presented. The beginning and end of mission surface fluxes show little variation, though the period towards mid-nominal mission does experience a maximum in total daily dose levels. Diurnal profiles are calculated highlighting the effects of increased scattering towards shorter wavelengths. A possible dust storm scenario is presented, and the effect upon component UV fluxes is shown to reverse the relative contributions of direct and diffuse components of the total UV flux. The presence of cloud formation above the landing site will be detectable though the observation of elevated diffuse/direct flux ratios. Near-surface morning fogs show a characteristic ‘dip’ in the morning profile when compared to clear mornings, allowing their detection on cloud-free mornings through post-event analysis of long term data. Predicted Phobos eclipses are investigated at each of the sensor centre wavelengths, and show greatest reduction in relative intensity at short wavelengths. Observations of near-miss eclipse events will also be possible, through monitoring of the diffuse UV flux. Dust devil encounters are shown to create a double minima lightcurve, with the depth of the minima dependent upon the total dust loading of the vortex. The effects of these changing conditions on DNA-weighted irradiances are investigated. Possible dust storms provide the greatest increase in biological protection, whereas expected cloud formations at the Beagle 2 site are found to offer negligible protection. Within just five minutes of landing > 95% of any Bacillus subtilis-like bacteria present on the surface of the craft will have lost viability.
