SpaceX’s test flight of its next-generation Starship rocket was deemed a success, despite a bit of an explosive landing.As part of the launch, SpaceX attempted to perform a “flip landing” of the rocket. Although the flip landing resulted in the rocket blowing up, the finish was not unexpected.“Lot of things need to go right, so maybe 1/3 chance,” SpaceX founder Elon Musk said last month about the odds of the rocket nailing the landing.The rocket’s mission was not to leave Earth’s atmosphere, but to test several parts of the Starship rocket.“This suborbital flight is designed to test a number of objectives, from how the vehicle’s three Raptor engines perform to the overall aerodynamic entry capabilities of the vehicle (including its body flaps) to how the vehicle manages propellant transition. SN8 will also attempt to perform a landing flip maneuver, which would be a first for a vehicle of this size,” SpaceX said before the flight.SpaceX said even if not everything went correctly, there would be plenty to learn from this test to improve on future flights.“With a test such as this, success is not measured by completion of specific objectives but rather how much we can learn, which will inform and improve the probability of success in the future as SpaceX rapidly advances development of Starship,” SpaceX said.Musk deemed aspects of the launch a success.“Successful ascent, switchover to header tanks & precise flap control to landing point!” Musk tweeted.The rocket remained airborne for over six minutes, and it was slated to reach an altitude of 41,000 feet. 1591

Should you pay sales tax on your online purchases?Chances are good you already do, even though the law requires online retailers to collect the tax only in states where they have a physical presence.Amazon and Walmart, two of the giants of online retailing, collect sales tax on all their sales in the 45 states that have a statewide sales tax.But many other smaller retailers don't collect sales tax unless they have a physical presence in the state where the buyer lives, relying on a 26-year old Supreme Court decision that was related to catalog retailers. Many of the sales on Amazon's and Walmart's sites are actually done by smaller retailers using those sites as their platform. For example, Amazon says half of the sales on the site are by small and medium size retailers.On Tuesday the Supreme Court is hearing arguments whether to overturn its 1992 decision when it hears a new case focused on online purchases, South Dakota vs. Wayfair.A reversal could mean that all online retailers must collect sales tax everywhere. It's an issue that brick-and-mortar retailers insist will provide a level playing field with online competitors, and help to provide state and local governments with the tax revenue they deserve."The current tax system favors online retailers over brick-and-mortar businesses, and undermines fair and open competition in the marketplace," the National Retail Federation argues in a brief it filed in the case.President Donald Trump has claimed Amazon doesn't collect sales taxes, even though the company does.The Trump administration will join the oral argument in favor of online retailers being required to collect sales taxes everywhere.Those fighting the change say that it would impose an undue burden on small retailers who would owe not just state sales taxes but local sales taxes that many states and counties also impose. Wayfair argues more than 16,000 different taxing units could demand sales tax collections.South Dakota says it is looking to start collecting taxes only for future online sales, but But Wayfair's attorneys argue in court filings that many other states and local governments could demand years of back sales taxes, forcing retailers to go through costly audits of past sales and make back payments that could bankrupt some companies."South Dakota's choice to forego its remedy for back taxes in the event that the Court were to overrule [existing law] will not limit the retroactive application of such a ruling with respect to other state and local jurisdictions," said Wayfair's attorneys.And while the issue is portrayed as one of fairness for small brick-and-mortar retailers that have to compete against online retailers, experts say those small retailers could be among the ones that get hurt.Many small retailers depend on online sales. If they have to start complying with the complexities of collecting and remitting sales taxes nationwide, many could be forced to abandon that part of their business."Those smaller retailers are now starting to see an ability to compete with the big guys like Amazon and Walmart," said Sam Cinquegrani, CEO of ObjectWave, a digital strategy and services firm. "Now it might be something else that is going to take them back a step." 3256

September saw the highest number on record for family members crossing the US-Mexico border in a single month, the Department of Homeland Security said Tuesday.The figure could help fuel President Donald Trump's?calls for stricter immigration policies, a key issue he has been citing on the campaign trail in the closing weeks of the midterm election season.According to figures released by Border Patrol as part of its annual end of fiscal year numbers, 16,658 family members were apprehended crossing the border.The numbers were close during the 2014 unaccompanied minor crisis, when there were 16,330 apprehensions in June that year, and also close to numbers in December 2017, when 16,139 family members were apprehended on the southern border.2018 saw the most family apprehensions on the southern border, a DHS spokesperson said. The DHS data released Tuesday goes back to 2013.Overall apprehensions on the southern border in 2018 were also up slightly, at 396,579, up from 303,916 in 2017, but down from the previous year and in line with the last five years.The total is nowhere near the highs seen in the early 2000s.Senior administration officials told reporters Tuesday they have seen a steady increase of unaccompanied children and families compared to single adults apprehended illegally crossing the southern border. The officials spoke on a conference call under condition they not be identified by name.In September, almost 50% of those apprehended were family members and unaccompanied children. Last September, 32% were family members and unaccompanied children.The officials say that in 2000, 90% of those crossing illegally were single adults.The vast majority of family members apprehended come from the northern triangle countries of Guatemala, El Salvador, and Honduras, according to the officials, who say 75% of the unaccompanied minors come from Central America.The spike in family crossings has followed Trump's move in June to reverse his administration's "zero policy" that led to family separations. The widely criticized separations themselves followed an uptick in statistics for border crossings, and the new report on the surge in families entering the US comes just weeks before the midterm elections, which Trump has tried to make in part a referendum on immigration. 2316
